Family Practice Residency Clinic

Knapp / UTRGV Family Practice Residency Clinic

A new Knapp Medical Center / UTRGV Family Practice Residency Clinic is scheduled to open in late August, 2017 in Mercedes, at the northwest corner of Expressway 83 and N Mile 2 W Road (2810 W. Expressway 83, Mercedes TX 78570).

The historic new program for the Mid-Valley of South Texas is located in a new 13,800-square-foot building. The new program represents an expansion of medical education into the Mid-Valley.

“The Knapp / UTRGV Family Practice Residency Program will help create more opportunities in the Mid-Valley for those who would like to receive training as family medicine physicians,” said Rene J. Lopez, Chief Executive Officer for Knapp Medical Center.

“In addition, the educational and clinical components of this exciting project will be great assets for the entire Mid-Valley, thanks to our partnership with the University of Texas Rio Grande Valley School of Medicine, the City of Mercedes, and the Knapp Community Care Foundation,” Mr. Lopez added.

The new program is under the direction of Dr. Miguel Tello, Associate Program Director for the Knapp Medical Center / UTRGV Family Practice Residency Program

First Group of 6 Family Practice Residents

Six new family practice residents formed the inaugural class for the program: Dr. Miguel A. Sanchez Rivas, Dr. Marita del Pilar Sanchez Sierra Marino, Dr. Diego Moreno, Dr. Eliana Costantino Burgazzi, Dr. Eddy Berges, and Dr. Carolina Gomez de Ziegler.

Dr. Tello noted that this first group of residents is an experienced group of physicians, who have served patients in various settings – ranging from colonias in the Valley to remote jungles and other challenging environments in South America and elsewhere.

“We needed a seasoned group of physicians who would be able to handle the stress of being a first-year class,” Dr. Tello added. “Their varied experiences and backgrounds really add a unique dimension to this class.”

One of the residents, Dr. Eddy Berges, who practiced medicine in the Dominican Republic and Puerto Rico before coming to the Valley, noted that family medicine physicians provide a wide range of services, including preventive health, to people of all ages, ranging from children to senior adults.

“I think it’s a very complete specialty where you can take care of everything for a person, for her environment, her family,” added Dr. Carolina Gomez de Ziegler, who practiced medicine in Venezuela before coming to the Rio Grande Valley.

Hours of Operation:

Monday through Friday, 8 a.m – 5 p.m. (starting late August, 2017)
